The following outline is provided as an overview of and topical guide to critical theory:
Critical theory – the examination and critique of society and culture, drawing from knowledge across the social sciences and humanities. The term has two different meanings with different origins and histories: one originating in sociology and the other in literary criticism. This has led to the very literal use of 'critical theory' as an umbrella term to describe any theory founded upon critique. The term "Critical Theory" was first coined by Max Horkheimer in his 1937 essay "Traditional and Critical Theory".
Private sphere – certain sector of societal life in which an individual enjoys a degree of authority, unhampered by interventions from governmental or other institutions. Examples of the private sphere are family and home. The complement or opposite of public sphere.
Public sphere – area in social life where individuals can come together to freely discuss and identify societal problems, and through that discussion influence political action. It is "a discursive space in which individuals and groups congregate to discuss matters of mutual interest and, where possible, to reach a common judgment."
